Proportional Directional Valve 4WRLD25V1-400L-4X/MXY/24TD6T - Bosch Rexroth R901502973

High pressure and high flow at the same time are the design point of this version: 350 bar operating pressure at 400 l/min nominal flow in size 25. Spool symbol V1 controls 4 ports across 3 switching positions, the pilot stage is fed and drained externally.

Key benefits

• 350 bar at 400 l/min nominal flow, up to 1250 l/min maximum flow.
• Spool symbol V1 in size 25 with internal spool position feedback for repeatable positions.
• External pilot oil routing on both sides keeps control pressure independent of the main circuit.
• Integrated digital axis controller, ±10 V command value, 24 VDC supply.
• 19.64 kg on a subplate to ISO 4401-08-08-0-05, 12-pole connector (11 + PE).
• NBR seals for HL hydraulic fluid in continuous duty.

Applications

The valve is used in presses, forging and rolling equipment and in test rigs with large cylinder areas. Where an axis must be fast and accurate at once, the integrated controller provides feedback without external electronics. The external control circuit allows separate filtering of the pilot oil.
